External file loading reference loading issue due to dynamic routing in angular?

问题

I am Using Angular Universal project. In that i have configured fully dynamic routing like below.

{ path: ':locale', component: HomePageCategory    },
{ path: ':locale/:id', component: HomePageCategory    },

Now i have added PWA so manifest reference was added in html file like below.

  <link rel="manifest" href="./manifest.webmanifest">

issue raised like below

1. Failed to load resource: the server responded with a status of 404 (Not Found)
2. Manifest: Line: 1, column: 1, Unexpected token.

can you please suggest to resolve this issue.

While loading page manifest was not fetched, due to routing configurations.
